Note (10588): Eric Gouda (2012-12-04) - Tillandsia subconcolor can be (the inflorescence looks much like it, except the acute spikes), but that species has cinereous lepidote leaves and brown lepidote sheaths. This specimen has glabrescent glaucous leaves!
It does look much similar to what I call Tillandsia reversa from Rio maranon, N.Peru (photo 6117). (Sent: brom-l@science.uu.nl)
